W5100 to Atheros AR9331 Bridge

I have an existing W5100 product which I connect to HANrun HR911105A.

For my new design I wish to remove the RJ45 and connect directly to one of the port on this Domino AR9331 based product.

Can this be done successfully? Is there any recommendations for doing this?

No one at Wiznet can help?
